Meet Sarah Johnson, fitness DVD addict. The 32-year-old Alexandria, Virginia, resident considers her hand-picked collection of workouts her "prized possessions," particularly the titles featuring instructor Shaun T. ("He helped me lose 30 pounds and so many inches," she says.) Johnson loves progressing through a familiar routine. She feels like she's become buddies with the folks on screen.
So why doesn't Johnson have plans to buy any more DVDs — not even this month, the biggest time of year for the fitness industry? There's simply too much competition for her muscles.
